     * Why it happens? Because SlickGrid can resize problem when the DOM element is hidden and that happens when user doesn't wait for the grid to be fully rendered and go in a different Tab.
     *
     * So the patch is to call a grid resize if the following 2 conditions are met
     *   1- header row is Y coordinate 0 (happens when user is not in current Tab)
     *   2- header titles are lower than the viewport of dataset (this can happen when user change Tab and DOM is not shown),
